I don't know if it is as bad as the turbo 606's (with a MAF and a MAP) but if it does, ensure that there are no intake leaks between the MAF (Mass/Air flow meter) and the MAP (Manifold Absolute Pressure) sensor; the 606 nanny looks for a calculated drop in manifold pressure and a reduction in intake airflow when the EGR is open... And I think it will pop open the EGR every once in a while just to test things... Any significant differences==NoBoostForYou! (does invoking the soup Nazi count as far as Godwin is concerned ?)
